Yesterday Patrick Hogan and Borbala Szeles have been in the field to calibrate the Eddy covariance devices. Borbala will now gradually take over the responsibilty for the weather station installations with the support of Patrick.

For the calibration a dew point generator was used. This device is used for providing a stream of gas with a precisely controlled dew point which for example is used for calibrating the H₂O channel of gas analyzers.
